The state of one document as it stood on one date. Pure lookup, no ranking. mode=outline lists the provisions (articles/annexes) without text — use it first on long documents; mode=select returns only the named anchors' text; mode=full (default) returns the whole text. Every provision carries its own permalink and hash.

Every state a document has been in: validity intervals and version keys, publisher-asserted.

The set of works in force on a date, computed from validity intervals at query time, deduplicated by work. Carries a mandatory population disclosure.

What changed between two dates for one work: which versions applied, and where both texts are held, retrieve them via as_of to compare.

Filtered-then-ranked full-text search (FTS; filters always run before ranking). Returns hits WITHOUT body text: lex_id, dates, snippet, hash. Full state via as_of.

Every distinct text ONE provision (article/annex) has had, as validity intervals — plus its lifecycle events (inserted/removed/renumbered, renumbering detected mechanically by identical text hash). The answer to "what did Article X say over its life / when did it change".

Proof chain for one lex_id: source URI, retrieval time, record/body hashes, event chain, corpus commit, index build, stamp signature.

What we hold and what we lack, tier by tier: counts, date ranges, history_begins, known gaps. This tool exists to say what we do NOT have.

Which ARTICLES point at this law. The reverse of the cross-references the publisher writes into its own text ("modifie par la loi du 4 juin 2020"), captured at derive time. Answers "what depends on this law", "who amended it", "is anything still referring to it" — the question legal research is actually made of, and the one a search box cannot answer.

ACROSS the corpus: which works gained new versions between two dates, how many each, and when — the aggregate counterpart of diff/timeline (which cover ONE work). Use for "what changed between 2025 and 2026", "which laws changed most during the pandemic", "what moved last month". order=by_churn ranks by number of new versions; by_date (default) lists most recently changed first.
